Nearly everyone uses glass bottles and needs lamps, so why not make a lamp out of a used bottle? Here are two ways you can get this project done, either with a traditional tungsten filament or a more modern LED.

Instructables user bkhurt created his LED gel-filled bottle lamp out of an empty wine bottle, a cork, some wire, blue and red LEDs, 220 Ohm and 100 Ohm resistors, a small toggle switch, and gel candle wax. You can pick up the gel wax at most craft stores (like Michaels) and the rest from RadioShack (or a similar store). The bottle, of course, can just be any glass bottle you have lying around. You'll also need a drill, a glue gun, a pot, food thermometer, and a few other tools to make this project happen, but despite the intimidating list bkhurt provides the project looks pretty straightforward.

Alternatively, Instructables user Random_Canadian has a tungsten filament-based bottle lamp if you prefer incandescent light. This project looks a little more complex and requires a vacuum pump—among other things—but definitely has a unique style and quality of light that some may prefer.

Either way, hit up Instructables for the detailed how-tos. Both projects can add give you an awesome new lamp while saving a glass bottle in the process.
